Wreckin' crew

Its a bit like a jigsaw but square. These block pavements never fail to amaze me. You have somebody who has a bit of talent cutting these bricks to all sizes and shapes who then creates his blank mosaic in the template before him.
A few months down the road and one of the utility companies come along dig it up and chuck the bricks into the back of a dumper truck and then fills in the hole with tar.
